The HTC One Duo Camera hardware

The rear of the HTC One (M8) has two camera elements. The first is the UltraPixel sensor that was introduced on the 2013HTC One. It's the same sensor in the 2014 model, with the same 4-megapixels of resolution, with each "pixel" being 2-microns at sensor level. That's much larger than its rivals, with the aim to capture more light for better quality results.

The second element is the Duo Camera. A lot of people will be asking about the megapixels this camera captures, but that's not primarily how it works. The secondary sensor is there to capture depth information. HTC hasn't released any other technical data about the Duo Camera at this time, but its purpose is to provide information for use in post-processing for some quirky results.

This is not a 3D camera

It's important to understand that this is not a 3D camera, the likes of which we saw on the LG Optimus 3D or HTC Evo 3D. This isn't about stereoscopy, although some of the same principles apply to the Duo Camera as they do to 3D capture.

So what can Duo Camera do?

Duo Camera opens up a number of features on the HTC One (M8). The data it captures is fed into the imaging engine - taking advantage of the power that the Qualcomm S4 Image Signal Processor offers - in tandem with proprietary HTC technology.

At the point of capture, the Duo Camera doesn't give you additional shooting options. It needs to be uncovered for the camera to work, but it's the data that's important, as it's all about post-shooting modifications.

There are four editing options that take advantage of data that the Duo Camera collects: Ufocus, Foregrounder, Seasons andDimension Plus. These leverage this depth information in different ways, giving you effects applied in a unique way that is fun. However, these effects can be hit and miss when it comes to precision accuracy.

What is Ufocus?

Ufocus is an editing mode that will let you switch the focal point of an image after shooting. This isn't like Nokia Refocus which captures a series of shots; this can be applied to any photo you take on the HTCOne (M8) after the fact (as long as it's not a close-up). This concept is great.

Ufocus can also use the captured depth data to apply a blurred photographic effect behind a subject typically used for that pro portrait look. This produces a shallow depth of field type of look typical of pro cameras with wide aperture lenses; that melty out-of-focus background effect is known as bokeh, which will be one of those hot words you'll be hearing a lot more
